To achieve fine tuning, the mounting plate 4 is connected to the movable part of the fine tuning device 3.

As shown in fig. 3, the mounting plate 4 includes a plate body 401 and a fastening mechanism, the plate body 401 includes a handle and a U-shaped storage groove, and the plate body 401 is fixed to the fine adjustment device 3 by the handle, specifically, the handle is connected to a movable portion of the fine adjustment device 3.

The U-shaped storage groove is used for storing a handheld coarseness gauge or a mounting frame 5, and the handheld coarseness gauge or the mounting frame 5 is fixed with the plate main body 401 through a fastening mechanism. One U-shaped side edge of the two U-shaped side edges of the U-shaped storage groove is arranged close to the handle of the plate main body 401, the other U-shaped side edge is arranged on the opposite side, and the measured object is located on one side far away from the handle of the plate main body 401.

The fastening mechanism of the mounting plate 4 comprises a bolt column 402 and a first positioning hole 403, wherein the bolt column 402 is arranged on the inner wall of one U-shaped side edge of the U-shaped storage groove, and the first positioning hole 403 is arranged on the top of the other U-shaped side edge of the U-shaped storage groove.

As shown in fig. 4 to 6, the mounting frame 5 includes a frame body 501, a bolt hole 502, a bolt post hole 503 and a pre-tightening hole 504, the frame body 501 is hollow, the top and the side far away from the fine adjustment device 3 are open, the bolt post hole 503 is located on the outer wall of the frame body 501 and corresponds to the bolt post 402, the bolt hole 502 is located on the outer wall of the frame body 501 and corresponds to the first positioning hole 403, and the pre-tightening hole 504 is arranged on the side wall of the frame body 501.

The frame body 501 is used for mounting a hand-held coarseness gauge, and its shape can be adjusted according to the external shape of the hand-held coarseness gauge to be mounted. Because conventional hand-held coarseness appearance is the cuboid, consequently, frame main part 501 is the cuboid preferably, and the open-top of cuboid is for dodging hand-held coarseness appearance, lets hand-held coarseness appearance put into frame main part 501 inside, and the one side that micromatic setting 3 was kept away from to the cuboid is the opening for dodging hand-held coarseness appearance's measuring pin, lets the measuring pin stretch out frame main part 501 and accomplish the measurement to the measured object.

The pre-tightening hole 504 on the mounting frame 5 is used to limit the handheld coarseness gauge in the frame body 501, for example, the pre-tightening hole 504 is a threaded hole, and the screw is abutted against the handheld coarseness gauge after penetrating through the pre-tightening hole 504. In this way, the number of the pretensioning holes 504 is preferably plural, and the plurality of pretensioning holes 504 are relatively distributed on both sides of the frame body 501. Of course, the pre-tightening hole 504 may be provided on only one side, the hand-held coarser gauge may be abutted against the inner surface of the other side of the frame body 501 by the screw, and the hand-held coarser gauge may be limited by the screw on one side and the inner surface of the frame body 501 on the other side.

In other embodiments, the pre-tightening aperture 504 may also limit the hand-held coarseness gauge in other various ways. The mounting of the handheld coarseness gauge may be accomplished, for example, by mounting the clamping structure through the pre-tightening holes 504 and clamping the clamping structure. In another example, an elastic rope is installed on the pre-tightening hole 504, and the limit of the handheld coarseness gauge is achieved through the elastic rope, so that the stability of the mode is poor.

In addition, the latch post 402 may be a rigid structure or an elastic structure, and if the latch post 402 is a rigid structure, the U-shaped storage groove of the plate main body 401 needs to have a sufficient length to complete the placement of the handheld coarser instrument or the mounting frame 5, and if the latch post 402 is an elastic structure, the U-shaped storage groove of the plate main body 401 is slightly larger than the handheld coarser instrument or the mounting frame 5, so that connection can be achieved. When the handheld coarseness gauge or the mounting frame 5 is embedded in the U-shaped storage groove of the plate main body 401, the bolt post 402 is inserted into the bolt post hole 503 to realize left and right limiting of the handheld coarseness gauge or the mounting frame 5.

As shown in fig. 7 to 8, the latch tab hole 502 is fastened to the first positioning hole 403 by the latch tab 404, the latch tab 404 includes a tab main body 4041, a second positioning hole 4042 and a tab protrusion 4043, the second positioning hole 4042 is provided on the tab main body 4041, the tab protrusion 4043 is provided on one side of the tab main body 4041, the tab protrusion 4043 is shape-adapted to the latch tab hole 502, and the tab main body 4041 is attached to the connection plate main body 401 through the first positioning hole 403 and the second positioning hole 4042.

The sheet body 4041 has a plate-like structure, and the sheet body 4041 is attached to the plate body 401. When the handheld coarseness gauge or the mounting frame 5 is embedded in the U-shaped storage groove of the plate main body 401, the sheet protrusions 4043 are inserted into the bolt sheet holes 502 to achieve left and right limiting of the handheld coarseness gauge or the mounting frame 5. The first positioning hole 403 and the second positioning hole 4042 are threaded holes, the screw is screwed into the first positioning hole 403 and the second positioning hole 4042 to fasten the plate body 4041 and the plate body 401, and the bolt column 402 and the bolt piece 404 cooperate to achieve front and rear limit of the handheld coarseness gauge or the mounting frame 5.

Of the first positioning hole 403 and the second positioning hole 4042, only the first positioning hole 403 may be a screw hole, the screw rod of the screw penetrates the second positioning hole 4042 and then is screwed with the first positioning hole 403, and the nut of the screw abuts against the latch plate 404 to fasten the plate main body 4041 and the plate main body 401. In addition, the first positioning hole 403 and the second positioning hole 4042 may be formed by inserting a body having a shape suitable for fastening the sheet body 4041 and the plate body 401, not screw holes, but the stability may be poor in this manner.

Corresponding to the nature of the latch post 402, when the latch post 402 is of rigid construction, the U-shaped pocket of the plate body 401 needs to be of sufficient length, and the tab projections 4043 of the latch tabs 404 also need to be of sufficient length; when the latch post 402 is of an elastic structure, the U-shaped storage groove of the plate body 401 is slightly larger than the hand-held coarseness gauge or the mounting frame 5, and the length of the sheet protrusion 4043 of the latch sheet 404 may be slightly shorter. The principle is that after the hand-held coarser instrument or the mounting frame 5 is embedded in the U-shaped storage groove of the plate main body 401, the two ends of the bolt post 402 and the sheet bulge 4043 are necessarily abutted against the hand-held coarser instrument or the mounting frame 5, so that the front and rear limiting is realized.

Fig. 9 is a schematic view of the hand-held coarser machine directly mounted on the mounting plate 4, and fig. 10 is a mode of fixing the mounting frame 5 on the mounting plate 4 and then mounting the hand-held coarser machine through the mounting frame 5. It can be seen that the present embodiment enables flexible installation of various types of handheld coarseness gauges. When the hand-held coarser machine needs to be mounted directly on the mounting plate 4, the hand-held coarser machine needs to have a latch tab hole 502 and a latch post hole 503 similar to the mounting frame 5.
